A total of 10\(^{7}\)  \(^{197}\) Au(n,\(\gamma \) ) capture events and 3\(\times \) 10\(^{9}\)  background events were simulated to register about 10\(^{5}\)  coincidence events of each type in the individual detectors. The output of the MC simulation resembles that of the experimental set-up, including for each simulated event the deposited energy, interaction position and time of all the \(\gamma \) -ray hits in the S- and A-layers of the four i-TED modules. Experimental effects such as the low energy threshold, position and energy resolutions were included in the simulations to consider their impact in the imaging resolution (see Ref. [1]}) and consequently in the performance of the background suppression method.
